Centrifugally Cast Ductile Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.

Possessing high strength, good toughness as steel and better corrosion resistance than steel, the ductile iron pipe is the ideal substitute for gray cast iron pipe and common steel pipe. In addition, the DI pipes are produced with good straightness, even wall thickness, high dimension accuracy, smooth surface finishing and remarkable mechanical properties, plus with firmly sticking internal & external coating layer. Flexible Push-in joint and rubber gasket are used resulting in convenient installation of pipelines.

By combining amazing ductility and high tensile strength to the well established corrosion resistance qualities of ductile iron, this easily handled pipe can be readily tapped, drilled or welded. Ductile Iron Pipes offer unsurpassed benefits for applications in water supply, sewerage and gas mains by their reputation by actual performance!

Production Process

Application

1.Ductile iron pipes for water conveyance: Product standards: BS EN545:2002, ISO2531:1998
1) Pipes are supplied in standard length of 5.5/6.0m, short length pipes as per respective standards can be supplied.
2) In addition to Class K9 pipes, we also supply K7, K8, K10 and K12 classes of pipe.
3) The thickness can be determined by the formula e=K (0.5+0.001DN)
4) PFA (allowable operating pressure) is the internal pressure, exclusive of surge, that a component can safely withstand in permanent service.
5) PMA (allowable maximum operating pressure) is the maximum internal pressure, including surge, that a component can withstand for a relatively short duration, when either fixed above ground level or laid and back filled underground in order to measure the integrity and leak tightness of the pipek.

2. Ductile iron pipes for sewerage application:
Product standard: BS EN598:2002
Quality checks at every stage of manufacturing:
1) Strict selection of raw material is an indispensable requirement to produce quality ductile iron pipes and fittings.
2) We produces liquid metal suited to manufacture ductile iron pipes. The liquid metal is further processed in induction furnaces. It is then treated with magnesium for modularization and transferred to the centrifugal spun casting machines.
3) The pipes are heat treated, zinc coated, hydrostatically tested, tested, cement mortar lined and finished with a layer of bitumen coating.
4) The in process inspection and quality control at all points during the production cycle is strictly maintained and documented as ISO9001 quality systems.
